We’re not sure what Kim Kardashian thinks goes on in schools these days, but judging by her NSFW back-to-school range of merch, it’s got nothing to do with maths and science.

The reality star has outdone herself this time, serving up a smutty plethora of wildly rude equipment for when the kids start back at school this month.

For the forgetful, Kim’s selling Post Tit Notes for £8, or for just six quid, youngsters can get their hands on a ‘Send Nudes’ pin. Crumbs.

Busy mums and dads who might not have had time to get PE kits sorted can buy their little ones a pair of pool sliders emblazoned with the words, ‘Turbo Thot’, thot being short for "that hoe over there.”

Fans of Kim’s curves can get an assortment of memorabilia which pays homage to her bountiful rump, with portable butt-shaped chargers, butt-shaped USBs, a butt mouse mat and a sew-on butt patch all available.

Sadly, the butt air fresheners are all sold out.

There’s a whole new Kimoji keyboard available too, with beer, fake IDs and saucy homecoming queen corsets to choose from.

But the piece de resistance has to be a selfie pen, which features a nude image of Kim - although the rudey bits are blurred. It is for school, after all.

Needless to say, the internet was not impressed with the mother-of-two’s new goodies.

Yep, she's nekkid (Image: kimoji.com)

“What the f*** have I just seen? If anyone buys their daughter this you should be ashamed,” wrote one Twitter user.

"I just dont understand why anyone would buy these,” mused another.

In fairness to Kim, the terms and conditions on kimoji.com state that no-one under the age of majority, which is usually between 18 and 21 depending which US state you’re in, can purchase from the site.
